3MF & STL Viewer — MeshView

Open any STL, 3MF or ZIP download and see it instantly. That's the whole app. No ads, ever. No account. Nothing to dismiss between you and the file you just tapped. BUILT FOR 3D PRINTING MeshView is a fast STL viewer and 3MF viewer for anyone who prints. Tap a file from your slicer, a model site or a ZIP download and it opens. A multi-colour 3MF shows its own colours, including the filament colours a real Bambu Studio export stores, so an eight-colour plate looks like an eight-colour plate. For STL, which has no colour field, pick a filament colour yourself. MESHVIEW PRO Check a model before you waste filament on it. One lifetime purchase or a yearly plan. Never ads, never a video to watch. • Unlimited models • Point-to-point measure — tap two points on the model • Printability check — open edges, flipped normals, non-manifold edges and degenerate faces, with the problems highlighted right on the model and a plain verdict • Wall-thickness heatmap — thin, borderline and solid areas, with an adjustable minimum wall • Cross-sections along X, Y or Z • Separate-part detection • Wireframe, points and normals display • Six standard views: top, bottom, front, back, left, right • Millimetres, centimetres or inches New Pro features are included at no extra cost. Anyone who used MeshView before Pro keeps every Pro feature free. FREE • 3 new models a month; re-opening a model you've already viewed is always free. Pro removes the limit. • Open STL and 3MF, including multi-colour 3MF • ZIP downloads open directly; if a ZIP holds several models, you choose one • Rotate, pan and zoom — pinch and drag, or on-screen buttons when one hand is full • Isometric, top and front views, one tap each • Dimensions, triangle count, volume and surface area • Filament colours for your model • Orientation gizmo and scale bar, plus orthographic projection so what you see matches the part • Binary and ASCII STL, including files whose headers confuse other viewers OPEN FROM ANYWHERE Share a file to MeshView from Gmail, Drive, WhatsApp, your file manager — any app that can send a file. It lands straight in the viewer. YOUR FILES STAY ON YOUR PHONE Parsing and rendering happen entirely on-device. Your models are never uploaded, never sent to a server, never shared. There is no account and no sign-in. MeshView sends anonymous usage counts (like when the app is opened, or which format a file was) and nothing else. Purchases are handled by Google Play and RevenueCat; MeshView never sees your payment details. No filenames, no file contents, no exact measurements. HONEST ABOUT LIMITS Very large models are simplified automatically so the preview stays smooth, while the readout keeps showing your file's real triangle count. If a 3MF has brush-painted colour regions, MeshView tells you so rather than quietly showing the wrong colours: it reads painted files, but does not draw the painted areas themselves. We would rather tell you than pretend. The file parser is written in Rust and compiled to native code, so files open quickly and the app stays small. It does one job and gets out of the way.
